The stack trace printed by SA's "where" command does not show the class name of the frame's method. An example stack trace:

Java Stack Trace for main
Thread state = BLOCKED
 - private static native void sleepNanos0(long) @0x00007fdd53434d68 @bci = 0, pc = 0x00007fddc7543980 (Interpreted)

 - private static void sleepNanos(long) @0x00007fdd53434dd0 @bci = 33, line = 491, pc = 0x00007fddc753f166 (Interpreted)

 - public static void sleep(long) @0x00007fdd53434510 @bci = 25, line = 522, pc = 0x00007fddc753f166 (Interpreted)
